Review on 🥶 Efficient Winterization for Sprinkler Systems & Outdoor Faucets: Air Compressor Quick-Connect Plug with Solid Lead-Free Brass Blow Out Adapter Fitting by Bobby Posner

Overall build quality is very good, well machined finishes with no rough edges or burrs, solid construction. However, I only have to give this product 1 star as it does not fit my standard Quick Connect air compressor. He was a little big. I measured the diameter with my digital caliper and it was 0.465 inches (or 11.82mm). While my tire is full with the gauge I currently use with the same standard Quick Connect air compressor measured 0.451 inches (11.47mm). I'll try replacing it with another one to see if the next one is better.
